Abstract:This paper combines the extant literature and experiences to design a questionnaire to capture as many factors influencing trip chain,a common concept describing travel arrangement,as possible in order to completely understand what kinds of factors should be weighted in the policies.Then structure equation modeling technique is applied to finishing the confirmatory factor analysis by which those factors with significant impact are identified to make up of the factor set.Meantime the influence coefficients among the factors are computed based on the data samples.
